Walraven Male Thread Concrete Screw

This concrete screw provides a reliable anchoring solution for structural and mechanical fixings in cracked and non-cracked concrete, as well as pre-stressed hollow core slabs. Its M8 external thread connection, supplied with a Torx nut E7, ensures straightforward attachment of components and accessories. The zinc-plated steel body offers durable performance for internal environments, while the engineered tip and thread design limit spalling during installation. With up to three available anchoring depths, it supports flexible design choices and optimised stock usage. Fire resistance up to R120 and compliance with VdS CEA 4001 standards make it suitable for safety-critical applications, including sprinkler system installations.

• Very high load capacity: Supports demanding structural or mechanical loads.
• Approved for hollow core slabs: Suitable for precast pre-stressed hollow core substrates.
• Up to three anchoring depths: Provides installation and design flexibility across varying concrete thicknesses.
• Reduced edge and anchor spacing distances: Enables efficient installation closer to edges or adjacent anchors.
